MX MAGNACHIP SEMICONDUCTOR Corp Insider Trading

Director Nathan Gilbert E buys 22.0K shares of MX at $2.87; holdings rise 16.1% to 158.2K; stock -33.6% from 52-week high amid -22.8% revenue decline.

Director Nathan Gilbert E purchased 21,994 shares at $2.87 on 2026-03-16, increasing his holdings by 16.1% to 158,200 shares. The purchase occurs in a distressed context: MagnaChi Semiconductor reported revenue of $45,946,000.00 with net income of $-13,090,000.00, annual revenue decline of -22.8%, and the stock trades -33.6% from its 52-week high of $4.40. Notably, this buy follows two other purchases on 2026-03-13 and 2026-03-12 at the same company—a three-day buying sequence. Examining his prior trades at MX, timing results have been mixed: his 2025-03-13 buy showed a 90-day return of +6.8%, while his 2023-12-08 and 2023-08-15 buys resulted in 90-day returns of -17.6% and -19.8% respectively. His cross-ticker track record shows an average 90-day return of +9.5% with a 50% win rate, but same-ticker history suggests variable outcomes. The intensity and timing of the three consecutive-day purchases at a declining business warrant attention.

Director Nathan Gilbert E bought 38,006 shares ($104.9K) at $2.75–$2.79 on 2026-03-12/13; stock -35.0% from 52-week high, company unprofitable.

Nathan Gilbert E, a director, executed 2 separate purchases totaling 38,006 shares for $104,924.02, raising his holdings by +38.7% from 98,200 to 136,206 shares. The purchases occurred at $2.75 and $2.79, while the current price is $2.86 — showing the stock trading near the transaction prices. MagnaCHIP is operating under significant headwinds: revenue contracted -22.8% year-over-year and the company posted a net loss of $-13,090,000.00 in its latest full fiscal year. The stock is down -35.0% from its 52-week high of $4.40. His prior trades at MX show mixed timing outcomes (1 of 3 prior buys at this ticker achieved a positive 90-day return). This purchase adds shares to an already-material position at a depressed price point in a fundamentally challenged business.

Martino Camillo acquired 30,000 shares of MX at $2.84; stock down -42.7% from 52-week high and -30.4% in 30 days.

Martino Camillo purchased 30,000 shares at $2.84 on 2025-08-22, increasing his holdings by 13.1% to 259,127 shares total. The stock has since declined to $2.88 (current), reflecting a severe deterioration: -42.7% from its 52-week high of $5.03 and -30.4% over the past 30 days. MagnaChi's fundamentals remain stressed, with annual revenue growth of only +0.7%, negative full-year net income, and a market cap of $103,461,215.04 against quarterly revenue of $47,622,000.00. Camillo's own cross-ticker track record shows modest underperformance (2 prior buys with avg 90d return -5.1% and 50% win rate), while his prior two buys at MX produced mixed results: one gained +7.5% over 90 days; the other lost -17.6%. The timing of this purchase—amid steep recent price declines—occurs at a depressed valuation point but follows a pattern of modest success rates on his prior MX purchases.

Park Shin Young bought 10,000 shares of MX at $2.87; stock down 42.7% from 52-week high.

Park Shin Young purchased 10,000 shares of MagnaChi Semiconductor at $2.87 on 2025-08-25, increasing holdings from 241.8K to 251.8K shares (+4.1%). The purchase occurs against a sharply depressed stock environment: the stock trades at -42.7% from its 52-week high of $5.03 and is down 30.4% over the prior 30 days. However, this insider's historical record provides limited confidence in the timing judgment. His single prior buy at this ticker on 2024-03-12 returned -3.2% over 30 days and -10.8% over 90 days, with a 0% win rate across all prior open-market buys. The company itself faces fundamental headwinds: it generated $47.6M in quarterly revenue with only $323.0K net income, is unprofitable on a full-year basis, and showed anemic 0.7% annual revenue growth. This buy sits in the context of deteriorating stock performance and an insider whose prior trades have not demonstrated successful timing at this company.

Director Lee Ilbok buys 20,000 shares at $3.86; cluster pattern with 2 peers in 14 days as MX loses -29.3% from 52-week high.

Director Lee Ilbok purchased 20,000 shares at $3.86 on 2025-03-14, increasing his holdings by 10.0% from 199.2K to 219.2K shares, while the stock trades -29.3% below its 52-week high and has declined -8.9% over the past 30 days. The transaction occurs within a cluster pattern in which 2 other insiders also bought within the past 14 days, suggesting coordinated or mutually reinforcing confidence. However, the company's fundamentals show material challenges: net income was -$9.6M over the most recent full fiscal year with annual revenue growth of only +0.7%, making this purchase activity noteworthy against a backdrop of operational losses. The convergence of multiple insiders buying amid depressed valuation levels and trailing operational underperformance warrants close examination of whether this reflects insider view of a turnaround opportunity or simply contrarian buying at cyclical lows.

Director Nathan Gilbert E buys 20,000 MX shares at $3.68; cluster pattern detected with 2 other insiders buying in past 14 days

Nathan Gilbert E (Director) purchased 20,000 shares at $3.68 on 2025-03-13, increasing his holdings from 78,200 to 98,200 shares (+25.6% increase in position size). The stock is currently trading at $3.88, down 33.2% from its 52-week high of $5.81, and has declined 14.0% in the past 30 days. While the cross-ticker track record shows an average 90-day return of +12.3% on prior buys, his same-ticker history at MX shows 0 of 2 prior buys were well-timed at the 90-day mark (prior purchases in 2023 showed 90-day returns of -17.6% and -19.8%). A cluster pattern is present with 2 other insiders also buying within the past 14 days, suggesting coordinated interest at current price levels. The company reported $66.5M quarterly revenue with -$9.6M net income, reflecting ongoing unprofitability and minimal growth of +0.7% year-over-year.

Director Martino Camillo bought 20.0K shares of MX at $3.66, doubling holdings to 40.0K shares amid unprofitable fundamentals.

Martino Camillo (Director) purchased 20,000 shares at $3.66 on 2025-03-13, exactly doubling his shareholding from 20,000 to 40,000 shares. The purchase occurred while MagnaChi​p trades -33.2% from its 52-week high of $5.81 and the company reports -$9.6M net income on $66.5M revenue for the latest quarter. Notably, 2 other insiders also bought within the past 14 days, suggesting coordinated accumulation at a depressed price point. However, Camillo's own cross-ticker track record shows a 0.00% 90-day win rate with an average 90-day return of -17.6%, and his only prior purchase at this same ticker (2023-12-08) subsequently declined -17.6% over 90 days—a pattern that offers limited confidence in the predictive value of his purchase timing at MagnaChi​p.
